MARKING-PEN.

Specification of Letters Patent.

Patented Jan. 11, 1910.

Application filed December 7, 1908. Serial No. 466,383.

To all whom it may concern:

Be it known that I, LEE W. NEWMAN, a citizen of the United States, residing at La Crosse, in the county. of La Crosse and State of Visconsin, have invented a new and useful Marking-Pen, of which the following is a specification.

The objects of the invention are, generally, the provision in a merchantable form, of a device of the above-mentioned class, which shall be inexpensive to manufacture, facile in operation, and devoid of complicated parts; specifically, the provision of a reservoir, cap, tip, and feeder of novel and improved form; other and further objects being made manifest hereinafter as the description of the invention progresses.

The invention consists in the novel construction and arrangement of parts hereinafter described, delineated in the accompanying drawings, and particularly pointed out in that portion of this instrument wherein patentable novelty is claimed for certain distinctive and peculiar features of the device, it being understood that within the .scope of what hereinafter is thus claimed, divers changes in the form, proportions, size, and minor details of the structure may be made, without departing from the spirit or sacrificing any of the ad- 3 vantages of the. invention.

Similar numerals of reference are employed to denote corresponding parts throughout the several figures of the drawlngs.

1n the accompanying drawings, Figure 1 is a front elevation of my invention; Fig. 2

shows the same in vertical longitudinal section; Fig. 3 is a transverse section taken on the line AB of Fig. 2.

In carrying out my invention, I provide a reservoir 1 which may be of any form. Preferably, however, as shown, it is cylindricalin shape and of a length convenient to be grasped by the hand. The upper terminal of the reservoir 1 is provided with an inwardly projecting annular shoulder 2 threaded upon its inner face. The shoulder 2 is arranged to receive a cap denoted gen-' erally by the numeral 3, having a lower terminal 4 externally threaded to engage the shoulder 2 and internally threaded to receive the feeder which wlll be described in detail hereinafter. Integral with the upper terminal of the member 4 is the body 5 of the cap, arranged to extend laterally beyond The cap 3 is provided with 'an' axial bore 15 extending upward through the member 4 into the body 5 and internally threaded.

The tubular member 6 has an axial bore 16 extending downward into the member 5 of the cap and communicating at 11 with they axial bore 15 of the cap. 1 further provide a feeder comprising a body member 12 exteriorl-y threaded to engage the axial bore 15 of the cap. Rising from the body 12 of the feeder into abutment with the lower terminal of the tip 10 is a reduced neck 13 having an axial bore 14 extending from the upper terminal of the neck 13, downward through the body portion 12 of the feeder into communication with the reservoir 1. The body portion 12 of the feeder normally projects into the reservoir 1 beyond the lower face of the shoulder 2 and is transversely slotted at its lower end as denoted by the numeral 9.

Referring now to Fig. 2, it will be seen that the body portion 12 of the'feeder may be rotated in the axial bore 15 of the cap to bring the upper terminal of the feeder into abutment with the lower terminal of the absorbent tip 10. The axial bore 14 of the feeder is of such a size as to deliver a proper amount of the liquid contained in the reservoir l to the tip 10 through which it will pass by gravity and capillary attraction. As the tip 10 is worn away, a knife or coin may be inserted into the slot 9 and the feeder rotated, pushing the end of the tip 10 out of the tube 6 to the desired degree. It will also be noted that the reduced neck 13 of the feeder which is in abutment with the tip 10 is of smaller diameter than the axial bore 15 of the cap. By this construction, when the tip 10 is forced upward in the tube 6 as hereinbefore described, any portion or particles of the said tip which may be detached in its upward movement, will fall between the reduced neck 13 and the inner surface of'the member 4, the body portion 12 of the feeder preventing such particles from finding their way downward into the'reservoir 1, mingling with the marking fluid therein and impeding the working of the device. As clearly shown in Fig. 2, the body portion 12 of the feeder normally projects into the reservoir 1 beyond the face of the shoulder 2. By this construction, when the device is inverted and in use, any sedimentary matter contained in the marking liquid will tend to settle about the exterior of the body member 12, the position of the said body member 12 preventing the sedimentary matter deposited upon the lower faces of the shoulder 2 and the member 4 from finding its way into the bore 14 of the feeder, in which position it would tend to clog and impede the action of the device.

My invention is capable of a varied and extended application. In its larger forms it may be employed for marking packing boxes and package freight. In its smaller sizes it may be used for the hand cancellation of stamps. Generally, it is adapted for use in any case where it is desired to spread a relatively broad line of liquid upon a receiving surface.

The member 10 has been described as an absorbent tip, and in practice I prefer to fashion it from felt. Other materials may, however, be employed, the structure of the tip being dictated by the character of the material upon which the marking liquid is to be spread.

Having thus described my invention, what I claim as new and desire to protect by Lette'rs-Patent is 1. In a device of the class described, a cap having an axial bore threaded at its lower terminal; an absorbent tip slidably mounted in the upper terminal of the bore of the cap; a feeder-threaded to engage the lower terminal of the bore of the cap and having its upper terminal in abutment with the tip; and a reservoir assembled with the cap.

2. In a device of the class described, a cap having an axial bore threaded at its lower terminal; an absorbent tip slidably mounted in the upper terminal of the bore of the cap; a feeder threaded to engage the lower terminal of the bore of the cap and having its upper terminal in abutment with the tip, the feeder being provided with an axial bore communicating with the tip; and a reservoir assembled with the cap.

3. In a device of the class described, a.

cap having an axial bore threaded at its lower end and provided with a reduced upper terminal; a tip slidably mounted in the upper terminal of the bore of the cap; a

feeder mounted in the lower terminal of the bore of the cap, and comprising a body portion threaded to engage the lower portion of the bore of the cap, and a reduced neck rising therefrom into contact with the tip; and'a reservoir assembled with the cap.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
